Diastereoselective allylation of a chiral imine with allylzinc reagents: Diastereoselective synthesis of a novel broad spectrum carbapenem

Diastereoselective allylation of chiral imine with allyl-metal reagents was applied to prepare β-amino acid derivative as a key intermediate for the synthesis of a novel carbapenem 1. Combination of the allylzinc reagents and chiral imine, which was derived from L-valine methyl ester as a chiral auxiliary afforded a homoallylamine in good yield with excellent diastereoselectivity.

Stereoselective synthesis of a broad spectrum 1β-methylcarbapenem, J-114,870

An ultra-broad spectrum carbapenem, J-114,870 (1), was synthesized from the corresponding C-2 side chain and 1β-methylcarbapenem enolphosphate. Synthesis of the C-2 side chain was accomplished by installation of the benzene part to (4R)-hydroxy-2-pyrrolidone 3, affording 2-phenylpyrrolidine 8a, and asymmetric Michael addition of chiral amine to α,β-unsaturated ester derived from 8a.
